Merge two strings from a Json loop into one

I am trying to merge two strings from a Json loop into one. I have the following components in play at present. 

 

tFileInputJson-->tMap-->tFileOutputDelimited. 

 

My input json document looks like

{
"columns": {
"source": "config",
"column_details": [{
"columnname": "col2",
"datatype": "float"
},
{
"columnname": "col3",
"datatype": "integer"
}
]
}

}

 

I would like to create a string in tFileOutputDelimited as 

"The result set is

convert col2 to float

convert col3 to integer"

 

However due to the loop XPath query parameter being set to "/columns/column_details" in tFileInputJson and creating the string in tMap with columnname and datatype. I get the following output 

The result set is

convert col2 to float

The result set is

convert col3 to integer

 

Any help is appreciated. Thanks

Re: Merge two strings from a Json loop into one

Look at the tJavaFlex component, you have to code some java but pretty easy.
Something like below (didnt test the java code).

 

Basicly in the Pre part you set: 

String fullString = "The result set is ";

In the Main part (this will loop over all the rows) , you set :

fullString = fullString + "convert " + row.columnname + " to " + row.datatype + "\n"
